Temperature in degrees Celsius (°C) may be converted to degrees Fahrenheit (°F) as follows:

°F=(1.8×°C)+32

Concentrations of chemical constituents in water are given either in milligrams per liter (mg/L, parts per million), micrograms per liter (µg/L, parts per billion), nanograms per liter (ng/L, parts per trillion), or picogram per liter (pg/L, parts per quadrillion).

Datum

Horizontal coordinate information is referenced to the North American Datum of 1927 (NAD 27).
